 #### Scroll Timing
 
-You may want the default "out of the box" behaviour.  We schedule scroll after Ember's `render`.  This occurs on the tightest schedule between route transition start and end.
+You may want the default "out of the box" behaviour.  We schedule scroll immediately after Ember's `render`.  This occurs on the tightest schedule between route transition start and end.
 
 However, you have other options. If you need an extra tick after `render`, set `scrollWhenAfterRender: true`.  You also may need to delay scroll functionality until the route is idle (approximately after the first paint completes) using `scrollWhenIdle: true` in your config.  `scrollWhenIdle` && `scrollWhenAfterRender` defaults to `false`.
